Tackling the Wall – The Skip Way System, a new Approach to Steep-Angle Conveying in Quarries and smaller Open-Pit Mines

By F.-M. Wolpers Quarries and open-pit mines for ores, minerals or building materials are often characterized by steep terraced slopes formed by blasting and material removal. A new, energy-balanced steep-angle conveying concept is aimed to optimize operating costs and energy efficiency. Continue reading Tackling the Wall – The Skip Way System, a new Approach to Steep-Angle Conveying in Quarries and smaller Open-Pit Mines

The Dual Carry Conveyor (DCC) – What we have learned from 13 Years of Operation of the Namakwa Sands Conveyor

By G. Spriggs, J. Gerber The Dual Carry Conveyor (DCC) at Namakwa Sands was designed, constructed and commissioned by Tekpro Projects in 2002, complete with its unique ‘Pretzel’ top and bottom strand swop over system. As well as simultaneously carrying material in both directions, the DCC has also been extended over the years from its initial length of 3.5 km, via an intermediate length of 4.7 km to its current length of 6.3 km.

Pipe Conveying the next Stage: A new Technology for Steep Incline High Capacity Open Pit Conveying

By A. Minkin, P. Börsting, N. Becker A new conveyor design is set to help reduce conventional heavy-duty truck traffic and the resulting high operating costs in open pit mines. This article (ed. note: publ. 2016) presents the design and the initial findings of the feasibility study on the Chevron-Megapipe conveyor for a 350 m-deep open pit mine and a mass flow of 5000 t/h. Continue reading Pipe Conveying the next Stage: A new Technology for Steep Incline High Capacity Open Pit Conveying

Controlling Material Flow in Pits: Complete Plant equipped with Belt Scales

By L. Henke Belt conveyors are the standard for the transport of materials in pits and quarries. To control the material flow and the inventory of these materials, belt scales turn out to be the optimum choice, as they are easy to retrofit in existing plants. Continue reading Controlling Material Flow in Pits: Complete Plant equipped with Belt Scales

If Crusher-Availability counts: Failure to adequately maintain Crushers comes at a high Price

By E. JonesFunctioning crushers are of paramount interest for the production of many mines and quarries. The following article runs through maintenance tasks a user might take to prolong the service life of his crusher. Continue reading If Crusher-Availability counts: Failure to adequately maintain Crushers comes at a high Price

Titans in Texas: Coal for South Texas’ and Northern Mexico’s Power Stations

By M. AdamsM. LinnemannCoal deposits with thin seams and many interlayers can be mined economically by surface miners, which can cut the exact depth of the coal layer and deliver the coal ready for belt conveyance without further crushing. Continue reading Titans in Texas: Coal for South Texas’ and Northern Mexico’s Power Stations

Fortescue Metals starts Construction of USD 1.275 billion Eliwana Mine and Rail Project

Perth (WA), Australia – On July 5, 2019, Western Australian Premier Mark McGowan has turned the first sod on Fortescue Metals Group’s Eliwana mine and rail project. The USD 1.275 billion project includes the construction of 143 kilometres of rail, a new 30 mtpa dry ore processing facility (OPF) and infrastructure. First ore on train is expected in December 2020. Continue reading Fortescue Metals starts Construction of USD 1.275 billion Eliwana Mine and Rail Project

Overcoming a Mines Embankment: IPCC-system with new Belt Conveying Concept for steep Opencast Minewalls

By A. Minkin, F.-M. Wolpers, T. Hellmuth – In order to allow for a continuous high capacity conveying system out of steep walled open pit mines Thyssenkrupp together with Contitech and Siemens developed the Chevron Megapipe conveyor with an up to 900 mm outer diameter. The pipe belt features highest tensile strength as well as a ribbed carrying side to hinder the transported bulk material from rolling back. Continue reading Overcoming a Mines Embankment: IPCC-system with new Belt Conveying Concept for steep Opencast Minewalls

More economic Open Pit Mining: In-pit Crushing and Conveying System in Phosphate Mining

By U. Mentges Phosphate is an indispensable material for growth and thriving of plants, animals and men. As phosphate ore is only available in limited supplies in very few regions of the world it is of paramount importance to make extraction of the material as sustainable as possible. Continue reading More economic Open Pit Mining: In-pit Crushing and Conveying System in Phosphate Mining
